The real world difference between a tuned 2017 991.2 C4S 3.0 and a stock C4S

There are people out there that no matter how many graphs you show them of gains they just will not believe it. Well, you can ignore a dynograph but it is difficult to ignore what happens in this video.

You have two PDK 991.2's going at it one with a GIAC tune and one that is stock. Now, there is a lot of talking and some incorrect information (such as the C4S weight) to get through before they race.

Do yourself a favor and skip to the 3:50 mark:

Not much of a race, is it? They run again and the result is the same. The tuned car demolishes the stock car.

the only flaw that I see with this test is the fact that he is comparing a tuned pdk with a stock manual car. PDK cars are faster by design due to the fast shifting gearbox. PDK cars are at least a 0.5 sec faster on the 1/4 mile.

I wish he could find a stock pdk car and the tuned pdk car to compare. But tons of credit to him. I really like his videos.

didnt he say in the video that was he was borrowing his friends stock pdk 4S to test apples to apples? Did you watch the video?

In case you r getting itchy, DimSport piggy is decent. Almost stock torque curve until 6k and decent gain after (snapped back feel in 3rd and 4th). Plug and play.

Now that I'm about to cross the 10k mile marker and the warranty issue jitters have eased up a touch I may actually buy the AP and flash to the GTS map. Looking at the dynos it is more or less in line with what I'm looking for. Ideally, I'd like a tune that is a touch more aggressive than that but it can wait.

After driving my dad's Macan I'd want way more down low off the line. It comes on very slowly compared to my stock 991:2 and even a Macan Turbo I drove.

It needs a tune IMO.

Agreed, the car is a dog off the line, but two reasons I'd like a more conservative tune:

A. The factory tune limits boost to ~11psi in 1st and 2nd vs ~15psi in 3rd and up. Eliminating that alone would probably keep me happy for some time. I haven't gotten any clarity if the GTS has the same restriction, but that alone would probably account for 90% of the 0-60 difference between the two.

B. If that's not enough, an additional 50 ft lb off an unrestricted 1st and 2nd alone would be a huge gain. When you factor in the boost limit, the OTS stage 1 tune is probably about a 175ft lb increase in torque up to 60mph which is far more than I need or care to risk my pdk with. I'm actually pretty happy with how the car performs on the highway so I don't need much more to round the car out how I'd like it.
